Sometimes when skin is itchy, it's because bacteria are making it itchy by being naughty moving around really fast to make you want to scratch it. What they do, is they dance around frantically on you and run and stuff moving really fast to make it itchy. When you scratch yourself, you are spreading the bacteria to more places so they stop making you itch now you've given them what they want as they can not infest you more.
